Thermally sprayed zinc or aluminium in combination with organic coatings, TS Duplex Coating Systems, is a common method used for corrosion protection of bridges, ships and oil- and gas installations. These systems are supposed to provide a long lifetime (>20 years), and with that, be both cost effective and environment friendly. However, so far the potential market for these protective systems has not been reached. Potential users of such systems may have become sceptical because of some reported cases with rapid degradation. Particularly for systems were TS aluminium has been used, there have been problems. The main goals of this project have been to solve these problems, and to find an optimal protective system, which combines thermally sprayed metals with paint, and still have a relatively low price.
